Definitions

• the invention presents an adhesive for gluing paper posters to metal outdoor posting boards (billboards) and the process of production of this adhesive.
• the known adhesives widely used for gluing paper posters to outdoor wooden boards, based on polysaccharides utilize mechanical adhesion, i.e. glue penetrates pores in the glued materials: paper poster and surface of wooden posting board.
• polysaccharide alginate dissolved in water sodium or potassium salt of thereof
• cellulose or starch can be used.
• adhesive suitable to glue posters to metal boards can be obtained by mixing components containing appropriate amounts of poly(vinyl acetate) and / or diene polymer and/or arylic polymer and/or polysaccharide.
• the method of production of adhesive according to presented invention comprises of:
• the following examples present adhesive obtained according to the above described procedure, containing poly(vinyl acetate) with addition of plasticizer.
• This glue offers excellent adhesion properties in both porous and non-porous materials (substrates). The process of aging of this adhesive is slow, the obtained layer it is colorless and elastic.
• the elasticity of adhesive layer is increased by adding of dien polymer of butadiene.
• the application of acrylic acid increases resistance of adhesive layer to compression at different temperatures.
• the addition of styrene increases thermal resistance.
• the addition of butadiene results in increased resistance to effects of atmospheric conditions.
• the addition of styrene results also in good mechanical properties of the adhesive layer at low temperatures.
• Acrylate polymer included in the composition of the adhesive results in increased specific adhesion parameters, increasing adherence of the glue to metal sufraces.
• the addition of polysaccharide to the composition results in increased thickness.
• the addition of glycol increases elasticity of the adhesive layer and lengthens the drying time of the adhesive layer at the high temperature as well as it decreases the glue freezing temperature.
• the obtained adhesive is in the form of emulsion with consistency of a "thick cream".
• the density parameters can be adjusted by diluting adhesive with water.
• the adhesive After drying, the adhesive forms an elastic, insoluble-in-water layer of adherence and joining properties allowing subsequent applications of a few new layers of the adhesive and posters without the necessity of removing of previously applied layers.
• the adhesive can be stored at the temperature from 5 to 20°C.
• the shelf life of this adhesive is 12 months, during this time no changes such as ageing or play separation were observed all properties of adhesive were retained.
• the detail modifications of the adhesive for gluing posters to metal posting boards are presented in following examples.
• Adhesive for gluing posters to metal posting boards 10 parts by weight of water are introduced to the mixer, the paddle mixer is switched-on and the rotator is set for speed to ca 1000 rpm, next 45 parts by weight of polymer poly(vinyl acetate) containing 2% of diisobutylene in the form of dispersion containing 50% of water are slowly added. The mixture is stirred at the temperature of 25°C for 30 minutes, next 20 parts by weight of diene polymer containing copolymer of composition 50% styrene, 40% butadiene, 10% acrylic acid in the form of emulsion containing 45% of water are added.
• Winter type adhesive designed to be used at the temperatures from 0°C to -10 °C.
• Summer-type adhesive designed to be used at the air temperatures higher then 20°C.
• Summer-type adhesive designed to be used at the ambient temperatures from 5°C to 20°C.
• Adhesives prepared according to the herein described method characterize themselves in all of the above described chemical variations with high stability of the adhesive layer, elasticity and applicability with various types of poster with posting surface materials, such as metal or other materials like glass, modeling paste, ceramics, plaster and other.
